Thanks to a new ECO-MAX product line we are finally able to offer cost-effective antenna systems. These antenna systems cover majority of scenarios,
they are all listed below with their specifications. If you have any questions
please email for additional details. We can put together any combination of dipoles and yagis for you, either vertical, circular or horizontal polarisation. Also check at the bottom of description for recommended accesories.

YAGI systems:
These systems are not omnidirectional. Exact radiation pattern can be adjusted by setting an angle between yagi antennas. The wider you spread them the wider the signal will be. These systems are practical for example when you want signal only to cover 60-180 degrees. At least 4-6 yagi antennas are recommended for best performance. Gives best range of all three, but is more sensitive to multipath (just like the dipoles), for example systems 13-14.

Obtaining desired coverage patterns:
For high gain omni coverage use circular
or vertical dipoles. For custom directed patterns use 4-6 yagi antennas or more (systems 14-15). For perfectly omni-directional radiation pattern consider ExterminatorII antenna, it can be installed on top of the tower and the tower will not cause any shadow. It has gain comparable to 2 dipoles, polarization is vertical.

How much ERP will my transmitter have with certain gain?
3dbd gain: Your ERP will be increased 2x, for example 1KW transmitter will
have 2KW ERP*
6dbd gain: Your ERP will be increased 4x, for example 1KW transmitter will
have 4KW ERP*
9dbd gain: Your ERP will be increased 8x, for example 1KW transmitter will
have 8KW ERP*(*) not taking cable losses into account

Important: Due to large size and irregular shape of these packages the website
often gets shipping cost wrong. Also sometimes we have to use wooden case which
adds about 100 euro to the cost of antenna. For exact shipping cost please contact
our sales department, be sure to give them your exact address and they will
quote you shipping.

Recommended accesories: We recommend AA-230 ZOOM antenna analyzer for checking SWR of the antennas. Grounding kits can be purchased here, they ensure lightning protection. They should be installed at the antenna (if needed, most dipoles are grounded anyway), at the tower base and at the point of entrance into transmitter building. Also use self-sealing tape which turns into rubber and protects moisture from entering your antenna system.
